ALBERT J. DOTY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESNEASSIGNMENTS, TO THE GOODWIN GAS STOVE AND METER COMPANY, OF

SAME PLACE.

HEATING GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 390,352, dated Qctober2, 1888.

Application filed Marl-1126, 1887. Serial No. 232,517.

To aZZ whom, it may concern.-

Be it known that I, ALBERT J. Dor of Philadelphia. in the county ofPhiladelphia and State of Pennsylvania, haveinvented new and usefulImprovements in HeatingGas-Burners, of which the following is aspecification, reference being bad to the annexed drawings, forming apart thereof, in which- Figure 1 is a longitudinal section of a part IOof a heating gas burner constructed according to my improvement. Fig. 2is a plan view of the burnercap, and Fig. 3 is a plan view of the diskof which the burner-top is formed.

Similar letters of reference indicate corre- 55 sponding parts in allthe views.

In practice it has been ascertained that the best form for an orificefor burning a mixture of gas and air is an oblong slit; but in heatinggas-burners as usually constructed it is expensive and difiicult to formsuitable slits in the process of castiiiig or by means of sawing.

The object of my invention is to cheaply produce a heating gas-burnertop having a series of narrow radial slits for the escape of gas forburning.

The invention consists in the peculiar construction and arrangement ofparts, as herein after fully described, and pointed out in the claim.

In carrying out my invention I take a disk, A, of sheetiron or othersuitable material, and form in the edge thereof flaring slits a at equaldistances apart around the circu inferonce of the disk, the slitsextending inward from the periphery of the disk a distance equal to therequired length of the slit in the finished burner. I then, by means ofsuitable dies, swage up the disk so as to cause that portion containingthe slits to be beveled, as shown in (No model.)

case it is desired to attach a plate to the top of the burner, or if forany reason a plane surface of the disk is required, I leave the centerof the disk flat.

A The casting 13, forming the body of the burner, is of the usual shape,having the gas and air passage 0 turned upwardly at right angles at itsextremity and surrounded by a conical flange, (I, having at itsperiphery a lip, e, for receiving the edge ofthe disk A, as shown inFig.1.

The disk A is centrally apertured, and secnred to the casting B by abolt, j, which extends downward through the bottom of the casting.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent The herein-described gas-burner, consisting ofthe body B, having the air and gas passage 0 turned upwardly at itsextremity, and pro vided with the conical flange (Z, surrounding theupwardly-turned end of the said passage 0, and having the lip e, thesheet-metal burnertop A, having substantially a concave-convex form andprovided with a series of slits, a, in its downwardly-inclined rim, andthe boltf, for securing the top to the body, substantially as hereinshown and described.
